LangChain is an open-source framework that simplifies building applications using large language models. It helps developers connect LLMs with external data, tools and workflows and is available in both Python and JavaScript.
LangChain provides the engineering platform and open source frameworks developers use to build, test, and deploy reliable AI agents.
LangChain is a framework for building agents and LLM-powered applications. It helps you chain together interoperable components and third-party integrations to simplify AI application development — all while future-proofing decisions as the underlying technology evolves.
LangChain is a software framework that helps facilitate the integration of large language models (LLMs) into applications. As a language model integration framework, LangChain's use-cases largely overlap with those of language models in general, including document analysis and summarization, chatbots, and code analysis.
Welcome to LangChain # Large language models (LLMs) are emerging as a transformative technology, enabling developers to build applications that they previously could not. But using these LLMs in isolation is often not enough to create a truly powerful app - the real power comes when you are able to combine them with other sources of computation or knowledge. This library is aimed at assisting ...
LangChain has become the most widely adopted framework for building applications powered by large language models. With over 100,000 GitHub stars and millions of monthly PyPI downloads, it provides the abstractions developers need to connect LLMs to real-world data sources, APIs, and tools. This langchain tutorial walks you through building a complete RAG-powered chatbot from scratch in 13 ...
Learn what LangChain is, how it works, its core components including chains, agents, and memory, practical use cases in AI application development, and how to get started building with it.
LangChain is the easiest way to start building agents and applications powered by LLMs. With under 10 lines of code, you can connect to OpenAI, Anthropic, Google, and more.
